Accessibility Statement

Our target

DEIV's target is the Web Content Accessibility Guidelines (WCAG) 2.2, level AA.

Current status

DEIV partially conforms to WCAG 2.2 AA: some parts do not meet the standard yet. This status comes from an internal review carried out on 17 October 2026 with browser tests: keyboard use, Chrome's accessibility tree, contrast measurements and layouts at 320, 375 and 1366 pixels wide. It was not tested with a real screen reader, and some screens were not reviewed.

What works well

• On the screens reviewed, text in DEIV's standard colours meets a contrast ratio of at least 4.5:1 in both the light and the dark theme (a few labels do not: see Known issues), and the keyboard focus outline is clearly visible (measured in the dark theme, calculated for the light theme).
• The screens reviewed, the welcome steps, the sign-in screen and these Legal & Privacy pages reflow without horizontal scrolling at a width of 320 pixels.
• The sign-in screen has a labelled password field that accepts pasting and password managers, and its error messages are tied to the field.
• Each app screen reviewed has one main heading, landmarks and a help button in the same place, and focus moves to the content after navigation.
• Animations stop when your system asks for reduced motion.
• These Legal & Privacy pages work without JavaScript and have a skip link, the correct language for each translation, labelled navigation and tables with headers.

Known issues

• The side panel that explains where a number comes from is hidden from screen readers while it is open, and focus does not move into it.
• Some form fields, for example when you add a building, have visible labels that are not connected to the field, so screen readers do not announce them.
• The Simulation Map cannot be used with a keyboard alone.
• On the first visit to a section, the introduction card can cover controls that receive keyboard focus; on phones, the bottom tab bar can cover focused elements.
• Some dialogs and menus do not move or keep focus, some messages and results are not announced to screen readers, every screen has the same page title, and some single-key shortcuts cannot be turned off.
• Some text and borders have too little contrast: small labels on Realm › Newspaper (both themes) and on Calculators › Quality Research Cost (light theme), the borders of text fields and drop-down lists, and the footer text of the sign-in screen where it sits over bright parts of the picture.
• The welcome steps show two main headings at once, and after the last step focus is not placed on the content.
• The charts on Market › Product have no text alternative, and the search results of the command palette and of Market › Product are not announced as lists to screen readers.
• The moving parts of the Overview map and the LIVE price markers cannot be paused on the page (they stop when your system asks for reduced motion), and panning the Simulation Map or moving the Quick Calculator requires dragging.
• On phones, a few small links and controls are below the minimum target size, and with increased text spacing some labels are cut off.
• Not reviewed yet: Leaderboard, Realm (Buildings, Phases and Countries), Retail, Target Planner, Scenarios, Catalog, Chat and Alerts.

Fixes for these issues are planned.

If something in DEIV is hard to use, please tell the operator what you were trying to do, on which screen, and which browser and assistive technology you used.
